BA GGING MATERIAL.

-SPECIFICATION forming part of Letters Patent No. 245,892, dated August 16, 1881.

Application filed April 16, 1881. (N0 model.)

To all whom it may concern Be it known that I, ISAAC T. TICHENOR, of Auburn, in the county of Lee and State of Alabama, have invented a new and Improved Bagging Material, of which the following is a specification.

The object of my invention is to provide new and improved material for making bags, which is impervious to atmospheric moisture, is not destroyed as easily by the corrosiveaction of the contents of the bag, and is thus rendered stronger and more durable than the bags in use heretofore.

The invention consists in a coarse cloth, such as a burlap, which is covered on one or both sides with a mixture of clay and tar, so that this cloth will be thoroughly impregnated with the material.

In the accompanying drawings, Figure 1 is detail sectional elevation of any ordinary piece of burlap. Fig. 2 is a detail sectional elevation of a piece of the same treated with the mixture of tar and clay.

' or less clay may be mixed with a greater or less quantity of tar, according to the size of the meshes of the fabric. Thus, if the fabric is very coarse, the mixture must contain a comparatively greater quantity of claythat is, it must be stiff; but it the fabric is of a finer quality, the mixture must be more liquid-that is to say, less clay must be mixed with the tar. Glue, or adhesive material that will not be decomposed by the action of the air may be used in place of the tar. The bags or the bagging material A are immersed in this mixture of adhesive material and clay, or this mixture is applied on one or both sides of the bagging material with a brush until it is impregnated therewith, and both sides of the bagging material are covered by a layer, B, of this mixture of adhesive material and clay.

The bags treated in the manner described are impervious to atmospheric moisture, and are not so easily destroyed by the corrosive action of the contents. stronger and more durable than the bags in use at present. These bags are especially adapted for transporting lime, cement, fertit izers, guano, &c.

I am aware that a water-proof lining has been cohered to the inside of bags to protect the fabric from the acids contained in guano and other fertilizers, and that bagging has been saturated with the hydrate of lime for the same purpose; but the latter weakens the fabric and destroys the fiber, while, if used with phosphates, it renders the phosphoric acid insoluble and liberates the ammonia.

What I claim as new and of my invention 1. A process of protecting bagging material from the acids contained in guano and other fertilizers, which consists in saturating it with a mixture of clay and tar, said mixture being a solution of creamy consistency, as described.

2. A fabric for bagging purposes saturated with a mixture of tar and clay, as described.
